It's different. The textbooks used in ordinary high schools are generally mathematics textbooks specially designed for ordinary high schools by People's Education Press or other publishing houses. The math book of 3+4 vocational high school is a math textbook suitable for a secondary specialized college. The curriculum arrangement is simpler than that of ordinary high schools, which is more in line with the learning level of students of 3+4 vocational high school. Therefore, the mathematics textbooks of ordinary high schools are different from those of 3+4 vocational high schools.
